AUTOMA/DIC CUT-OFF DEVICE.

To all whom it may concern Be it known that I, IRA M. SPoNsEL, citizen of the United States, residing at Goodland, in the county of Sherman and State of Kansas, have invented certain new and use- .ful Improvements in Automatic Cut-Off Devices, of which the following is a specificat1on.

This invention relates to an improved automatic out off device.

When filling bottles, cans, and like nontransparent containers, it is often quite difficult to determine at just what time the liquid supply thereto should be cut off. It is to overcome this difficulty that the present invention isdesigned; said invention consisting of a float, a valve, and novel float controlled valve operating means; said means, and in fact the entire cut off device being associated with the discharge spout of a vat or like receptacle to automatically out off the liquid supply upon the delivery of a predetermined quantity to the container being filled.

In describing my invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a side elevation of a cut off device constructed in accordance with the present invention, the container to be filled being shown in section and partly broken away; and Fig. 2 is a longitudinal sectional view illustrating the position of the oper ating means immediately subsequent to automatic operation thereof.

Referring now to the drawings by numerals, 1 designates a vat or like receptacle containing the liquid supply, the said receptacle having associated therewith and mounted thereon adjacent its bottom a suitable discharge spout 2 the bore of which is open to the receptacle interior. Said discharge spout 2 is open, as indicated in Fig. 2, to a suitable substantially frusto-conical valve casing 3, the said casing being integral with the spout and open at its diverged end to provide for movement of a substantially frusto-conical valve member 4c, the latter, in one position, serving as a cut off means or closure for the spout.

Pivoted as at 5 to a lug or projection 6' of the valve is an operating lever 7, said lever being fulcrumecl' at a point intermediate its ends as at 8 in a bifurcation 9 of an arm or Patented Feb. 29, 1916.

Application filed August 31, 1914. Serial No. 859,539.

standard 10 secured to or integral with the spout. The opposite end of the arm 7, when the valve is elevated or forced into a position whereby to open discharge spout 2, is adapted for engagement with a suitable trigger 11 fashioned to represent a bell crank fulcrumed as at 12 in a bifurcation 13 of an arm or standard 14 also mounted on or formed integrally with said discharge spout 2.

-Trigger 11, as above noted, is in effect a bell crank, one end being provided with an integral lip or extension 15 adapted for overlapping engagement with the free end of arm 7 to normally maintain the said arm. in

a substantially horizontal plane whereby to ment serving as a guide means for the latter. The upper end or extremity of the said rod 16 is bent as at 18 to engage the trigger or hell crank 11, while the opposite end of the said rod has mounted thereon a suitable float or buoyant member 19.

When it is desired that a suitable nontransparent container be filled with liquid drawn from the receptacle 1, the said container, (as shown to advantage in Fig. 1) is positioned in such a novel and peculiar manner as to inclose the float 19. When thus positioned, valve member 4 is raised out of engagement with the casing 3 and the arm or lever 7 fastened beneath lip or extension 15 of trigger 11, the bent portion 18 of the operating rod 16 being also in engagement with the trigger. As the liquid contents of the container rise, the operating mechanlsm for the valve 4 remains inopera- Weight of valve member 4 Will cause the said valve to automatically seat itself in the position shown in Fig. 2 cutting off the liquid supply to the container and permitting only a predetermined quantity of liquid to be delivered thereto.

From the foregoing, taken in connection with the accompanying drawings it will be noted that the operation of the out 01f device is automatic, simple and positive; that said operation is controlled entirely by the rise of the liquid delivered to the container through the discharge spout With Which the cut off device is associated; and that valve member 4, the same being of suflicient Weight, Will cause the bore of the spout 2 to be positively closed immediately subsequent to disengagement of the trigger 11 With the operating lever or arm 7.

In reduction to practice, I have found that the form of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is

the most efficient and practical; yet realizing that the conditions concurrent With the adoption of my device will necessarily vary,

I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, Without sacrificing any of the advantages of my invention, as defined in the appended claim.

Having thus fully described my invention, What I claim as new and desire to secure by Letters Patent, is:--

A cut-off device for the discharge spout of a container comprising a float, a float rod to Which the float is attached, an extension formed on said rod to engage With the spout and support said float, an arm integral with said spout, a substantially bell crank lever carried by said arm in a plane directly above and in vertical alinement With said float rod to be engaged thereby upon movement of said float, an extension formed on one end of said lever, a pivoted operating lever mounted to engage With saidlast mentioned extension, said operating lever and said bell crank lever being disposed exteriorly of said spout, and a Weighted valve member pivoted to depend from the opposite end of said operating lever from that engaging said extension, said Weight d valve member being adapted to gravitate into an opening therefor in said spout to afford a cut-off for the liquid discharged therethrough upon movement of the bell crank out of engagement With said operating lever.

In testimony whereof I aflix my signature in presence of two Witnesses.
